CTD (Conductivity, Temperature and Depth) Sensor and
ADCP (Acoustic Doppler Current Profiler) Tow Profiles,
and Bio-optical Profile Transects

There are two towed systems as show above. A Small Water Area Twin Hull (SWATH) vehicle designed by GoldCoast Yachts and constructed by Rutgers is used to tow an RD Instruments Acoustic Doppler Current Profiler (ADCP) off the starboard side of the Caleta. The ADCP provides current profiles from top to bottom.

Towed behind our research vessel is a Guildline "Minibat" undulating tow-body equipped with a Falmouth Scientific Inc. (FSI) Conductivity Temperature Depth (CTD) sensor, a Wetlabs Fluorometer, and a D&A Instruments Optical Backscatter Sensor (OBS). The "Minibat" uses wings to fly between the surface and the bottom to provide full water column profiles of temperature, salinity, waterclarity and biological fluorescence.

The comprehensive ) optical instrumentation package aboard the R/V Walford (aka the Waldorf Astoria) includes a Wetlabs AC9 (absorption and attenuation meter at 9 wavelengths) and SaFIre (spectral fluorescence meter), Satlantic OCR (Ocean Color Radiometer) and Hyperspectral TSRB (Tethered Spetral Radiometric Buoy), Hobi Labs Hydroscat 6, Falmouth Scientific Inc. (FSI) CTD (Conductivity Temperature Depth), and LISST (Laser in-situ Spectral Transmissometer).

Below, is the calendar of the cruises we have taken. Just click on a date and you will see a map of where the cruise was, and cross sections of the CTD and ADCP data.
